Relative price DSE 答題技巧
做Econ past paper時遇到relative price的題目經常無從入手？
寫了一大堆東西卻只有一分？
不知道不同題型的提問關鍵字？
那麼，這篇文章一定十分適合你。
今天學博小編為大家整理了DSE常見的relative price題型，還會附上相應的答題flow及例題，希望能幫助到大家。
答題flow
-When a fixed cost is added to both high-quality _____ and low-quality _____, the relative price of high-quality _____ will decrease, relatively more high-quality _____ will thus be consumed.
-Proportion of high-quality _____ will increase.
-The average quality of _____ will improve/increase.
(如果係講緊搭的士/飛機，就將quality改成distance，其他variations仲有size，length等等)
例題
2021/DSE/II/2
Refer to the following taxi fare arrangement.
Original fare (whole day) |
First 2 kilometers $30 |
Every subsequent 200 meters $2 |
Suppose a late-night surcharge of $20 will be added to the original fare on any taxi trips from 1:00 am to 5:59 am. How will this surcharge affect the average travel distance of taxi passengers during late-night? Explain. (4 marks)
Marking scheme
When a fixed lump-sum charge is added on a good, the relative price of the long-distance trips will decrease but the relative price of the short-distance trips will increase. The quantity demanded of long-distance trips will relatively increase while that of short-distance trips will relatively decrease, so the proportion of long-distance trips will increase. The average distance traveled increases. (4)
